Improved traffic light management can help administrator to control vehicle flow and mitigate congestion, thus reducing transit time and associated carbon emissions. In addition to the basic function of a traffic light - Display Unit, with green, red and orange LEDs, it may incorporate a Detector Unit, with sensors for detecting vehicles or pedestrian and a Controller Unit - smart traffic light can be equipped with cameras to detect infringements to traffic code and registration plate recognition as well as connectivity to enable centralized control.
We have a broad range of wired and wireless connectivity – including sub-GHz, power management and supply and LED driving solutions, together with a range of high-performance and low-power STM32 microcontrollers, presence, proximity, camera and environmental sensors, as well as MEMS microphones to enable the design of advanced traffic lights systems.
